Arriving hungry and thirsty for an 'Organ Walking Tour' you have, somewhat dubiously, signed up for perhaps isn't the best way to give the experience its full chance. Part of Cambridge Summer Music Festival (not to be confused with various other concurrent music festivals in Cambridge) this tour involved an introduction to three chapels/churches by an art historian followed by short recitals on their organs. It sounded intriguing, and possibly good. And I think if, like 90%+ of the attending audience, you were signed up members of the 'We know everything about organs in Cambridge' fan club, it was probably fantastic. The boy and I had been more going for the 'get into a historic building and hear about it' part, so the first recital of loud, big organ sounds did nothing for us. It was nice to see Jesus College chapel though (formerly, before the Dissolution, the nunnery of St. Radegund). The second stop was more interesting: All Saints Church. Unlike Jesus, which had been redecorated in the revived Gothic style in the 19th century, this church was built as a showcase of revived Gothic. With the interior all recently restored, the coloured hand-painted wallpapered walls rather took me aback. It's worth a look if you are in the area. The final stop on the tour, sadly, was the boy's own workplace, so there was nothing new to see there.
